Dataset Abstract

This dataset contains the height, diameter and growth corresponding to the last 5 years from all juveniles, which were found in 16 subplots of 1m x1m, located in the central quadrant (in the upper half) of the main plot.

Dataset Design

Firstly, the regeneration plot (4m x4 m) was delimited in the central quadrant (in the upper half) of the main plot. After, the regeneration plot (4m x4 m) was subdivided in 16 subplots (1m x 1m). Within each 1x1m subplot, the juveniles and seedlings from the focal tree species were identified. Height, diameter and growth corresponding to the last 5 years were measured on juveniles.
